I am in the process of fitting an L18 and stanza 5spd into a 1200 coupe. we had to cut down the front crossmember (no big deal) and weld some plates across to suit the L series mounts. Engine fits really nicely. You need to use a sump with a well at the front (I got one off a stanza). The existing gearbox mounts need to be removed. The stanza 5spd fits quite snuggly in the standard manual tunnel, but you need to make up a new gearbox rear crossmember.( I used angle iron). I am using standard 1600 extractors which also fit quite snuggly.
Using the Stanza 5spd you dont need to change the gearstick hole. I am going to have to get a new tailshaft made up (quoted about $100). I have put in a 1200 ute diff. Other things to consider include changing the clutch over to hydraulic from cable. I am also struggling to find a radiator that fits. Also if someone can tell me what shocks they are running on a 1200 coupe with a ute diff I would be very happy, as I can't seem to track any down that fit.
